Here's the NFL.com draft analysis on Elliott:
Draft Projection
Round 5
Overview
Big, productive inside linebacker lacking the athletic traits to make enough plays on the next level. Elliott has earned praise for his exceptional work ethic and football character. His instincts and reaction time are average, though. He can be heavy-handed when taking on blocks and his execution is inconsistent. His pursuit speed to the sideline is too heavy-footed in pass coverage and as an open-field tackler. His pathway will need to be as a physical thumper who can star on special teams.
Strengths
High-end football character and trains like a pro at all times.
Revved up his production in second season at ASU.
Hands are heavy when he throws them with purpose at blockers.
Drifts downhill to help squeeze the run lane.
Makes himself big and wide as a wrap-up tackler.
Weaknesses
Poor speed leaves little margin for error in diagnosis.
Must improve at properly leveraging his run fits.
Lacks short-area quickness and reactive athleticism.
Slow to disengage from the block.
Can be exploited in the passing game.
